Is it possible to integrate the FileMaker with Facebook Marketing?
If, Yes Please send me the reference link.
FileMaker can integrate with most APIs and even some SDKs.
Facebook has an enormous amount of points of entry to integration. You weren't really specific on what exactly you want to do, but it's not a frequent integration for FileMaker so there's probably not a ready-made example specifically designed for you to use.
It's best to learn how to integrate APIs so you can develop your own integrations without relying on other's demo files.
That said, Here's Facebook's developer page: https://developers.facebook.com/
And their documentation which documents all of their different APIs, each with it's own details for consuming that API: https://developers.facebook.com/docs
For example here's the marketing API: https://developers.facebook.com/docs/marketing-apis/
